CEILING-PANEL.

SPECIFICATION forming part of Iletters Patent No. 440,008, datedNovember 4., 1890. Application filed July 8,1890. serial No. 358,077.(No model.)

To all whom it may concern:

Be it known that I, FRANK G. CALDWELL, a citizen of the United States,residing at Wheeling, in the county of Ohio and State of West Virginia,have invented new and useful Improvements in Ceiling-Panels, of whichthe following is a specification.

This invention relates to the metallic ceiling-panels described andshown in the Letters Patent issued to me August 27, 1889, No. 409,916,and October 29, 1889, No. .t14=,017.

The objects of my present invention are to improve the priorconstruction, to provide a ceiling-panel comprising an open wooden frameand a metal sheet, whereby the panels will so overlap each other thattwo edges of the metal sheet of one panel can be nailed to the edges ofthe open frames of adjoining panels, and thereby present an unbrokensurface, and finally to provide novel means whereby the open woodenframe of one panel can be nailed at two edges to the rafters or similarsupports and the projecting metallic edges of the adjoining panels canbe extended over and serve to conceal the nails or other fasteningsemployed to attach such edges of the open wooden frame.

To accomplish all these objects my invention involves the features ofconstruction and the combination or arrangement of elements hereinafterdescribed and claimed, reference being made to the accompanyingdrawings, in which-- Figure 1 is a plan view on a reduced scale, showingseveral panels in position as when applied to constitute a ceiling. Fig.2 is a detail perspective view showing one of the panels on a largerscale. Fig. 3 is a similar view showing the metal sheet corrugated. Fig.4 is a transverse sectional view of the panel, comprising a plain metalsheet stretched on the wooden frame.

In the accompanying drawings, exhibiting my invention, the numeral 1indicates an open wooden frame, which, as shown, is ap* proximatelysquare, but may be otherwise shaped in outline. This frame is rigid andcomprises wooden bars properly joined at their ends by suitablejoints-such as miters or tongues and grooves and to one surface of theframe is attached by nails or other fastenings 2 the metal sheet 3,which is tightly drawn or stretched. The metal sheet is so disposed onthe wooden frame as to project therefrom at two edges to formoverhanging flanges 4 and 5, running at right angles to each other ifthe frame is square or rectangular. By this arrangement the wooden framepro .jects at two edges to form supporting-ledges 6 and 7, which extend,respectively, parallel with the overhanging flanges of the metal sheet.In applying the panels to form a ceiling or similar surface they areplaced, as indicated in Fig. 1, in such manner that the overhangingflanges of a metal sheet overlie the ledges of two adjoining orvadjacent panels, and such flanges are nailed or otherwise secured tosuch ledges, as at 8, in such manner as to form practically an unbrokenmetallic surface.

In Figs. 1, 2, and at the metal sheet is shown plain or non-corrugated,and the overlying flanges are rigid, while in Fig. 3 the metal iscorrugated. The metal sheets are comparatively thin; but the woodenframe imparts the required stiffness, rigidity, strength, and durabilityto the panel as a whole, while rendering it possible to provide lightand easily handled panels, which can be rapidly assembled to produce aceiling or like surface. The exposed ledges of the wooden frame serve tonail or similarly attach the panels to the rafters or other overheadwork or supports without perforating the metal sheets for thepaneLattaching nails, and obviously the overhanging flanges of the metalsheets overlie and cover and conceal the nails or fastenings which passthrough the exposed parts or ledges of the open wooden frames. Theattachment of the metal sheet to one surface of the open wooden frameavoids the recess formed by the wooden frame in the exposed surface ofthe panel, as in my Letters Patent alluded to, and the whole provides auseful and desirable structure for obtaining practically unbrokenceiling-surfaces:

Having thus described my invention, what the panel and also serve assupports for ad- I claim isjacent panels, substantially as described. 10
